filters.cluster

The Cluster filter first performs Euclidean Cluster Extraction on the input PointView and then labels each point with its associated cluster ID. It creates a new dimension ClusterID that contains the cluster ID value. Cluster IDs start with the value 1. Points that don’t belong to any cluster will are given a cluster ID of 0.
